I have just a little more progress to report. I worked on my all in one control panel this afternoon. Got a good start on it. I'll get it all together soon. I have a micro motherboard that will go in here. The fan on the bottom of the power supply is nearly as big as the big fan in the photo. Don't think I'll need to move quite that much air. I have two smaller normal size fans that I'll stick in there somewhere.
I will need to put a filter on the outside somewhere as well. Perhaps on the back. I won't be cutting ANY MDF with this thing.
No fine dust. I use a dust collector in my shop too, so that will help. I will be hooking up a dust port for the router as well.
The box is .063 aluminum and 3/4" square aluminum tubing. All drilled and tapped with 10-24 screws. Could have used rivets, but just wasn't that sure I wouldn't need to take it back apart. Thought about powder coating it, but now that its going together....
The dimensions are 18" wide x 15" tall and 12" deep. Should be plenty of space in there. Thats it for now.
